Ok, it isn't all that amazing but I DO work in a Structural Engineering firm so "pretty pictures" aren't all the rage. But anyways, this a simple model of an Overhead Coverage System built over an existing structure to withstand incoming mortar and/or rocket fire. We've designed these to cover dining facilities, chapels, gymnasiums, and MWR (Morale, Welfare, and Recreation) facilities all over Iraq. And not only am I the draftsman, but I'm also on the survey team so I get to these projects through from Survey to as-built.
